Scenario: Fetch Row Details on Enter Action with Lead Selection.

Step1: Create a Webdynpro Component, go to Context and Create a Node as shown.

Note: Cardinality should be o:n and Selection should also be o:n as we are intending to select multiple rows .

endmethod.

Step 6: As we are suppose to make the table Input Enabled, provide the code for initializing the table in method WDDOINIT.

 DATA lo_nd_material TYPE REF TO if_wd_context_node.  lo_nd_material = wd_context->get_child_node( name = wd_this->wdctx_makt ).

  lo_nd_material>bind_table( new_items = lt_material set_initial_elements = 

abap_true ).endmethod.

Step 7: Bind your view to window.

Step 9: Provide the Material number using F4.

Hit Enter on the material number or click on the row selecting it as shown pointed.

As a result you will get the corresponding details of the Material Number entered.
